He loved her. She left him for someone richer.But that night, something awakened in Nishanth — a system with no fame boosts, no fantasy powers, and no second chances.Just money. Assets. Ownership.The Infinity Spend Protocol doesn't make him a hero. It makes him a Spend King — a silent force who crushes rivals, empowers the poor, and stuns the nation with outrageous moves.From the slums of Warangal to the boardrooms of Mumbai, Nishanth spends to dominate — buying failed properties, funding orphan tech labs, and humiliating those who once laughed at him.And when the world finally asks:“Who is behind all this?”He walks on stage and answers,“The boy you forgot. The man who never forgot you.”Spend. Dominate. Rise.This is the rise of India’s Spend King — a man who never needed fame.........Only the fire of betrayal.
